More than 630,000 people on the mainland were moved to safety yesterday as Typhoon Chanchu spared Hong Kong and veered towards Fujian province . Chanchu, the first to hit the region this typhoon season, was expected to make landfall near Shantou in Guangdong, or close to Fujian, early today. Xinhua last night reported that more than 307,000 people in Fujian had been evacuated from coastal areas and 42,000 vessels ordered to seek safe harbour. In Guangdong, 327,000 residents were moved to safety. Chanchu caused relatively little damage yesterday, but dozens of flights were cancelled or delayed in Shanghai, Guangzhou and Xiamen . Fujian Meteorological Bureau reported a few cases of landslides and flooding. Schools in Fujian were ordered to close and officials in Shantou have been put on high alert to prepare for Chanchu's landfall. In Taiwan, there were dramatic scenes when Chanchu grounded a small oil tanker off Kaohsiung. There were 13 crewmen aboard - nine from Indonesia and four from the mainland. They were airlifted from the vessel by a helicopter. 'The ship lost its mobility and started to tilt,' said a mainland crewman after the four-hour rescue operation. In Pingtung, huge waves swept two sisters away as they were having a barbecue by a rising river. Their bodies were found several hours later, police said. In Hong Kong, five people were slightly injured. Land, sea and air traffic experienced slight disruptions. At 9.30pm, 14 hours after the No3 signal was hoisted, the Hong Kong Observatory reverted to the No1 standby signal. At 1am, Chanchu was 310km east of Hong Kong and heading towards the southeast coast of the mainland at 30km/h.
